Reiem'i-Iig flow to vthe accompanying w- "io ings, in which l iso compensating gear ooeing and 2 end 2a the axle housings w weh `have their inner ends suitably bolted to the oomperisating gear housing at 3 nimy desired manner. A truss-rod 4 hes its @entrai .J5 portion supporting the under side of tiio oompensatirig gear' housing, and its outer ends 5 connected with the youter ends of the said eide Ahousings through the medium of e brake suppoiting member o which is carried 80 by the outer .ends .of the said housings.

Tire compensating gear maybe of 'any of' the wei known forms, but the preferred orm is that here'eoowi'i, eed it consists of e" bei# eed gear 'I which fie connected with twon 35 @part Isuie-irorising thetinoioses the comporrsoting piiiione 9.

seid ooeniege one. the mier .ends of the of tiiel @si are snede of e As `hele lit, but will readily permit the removal and insertion ci' the inner ends of the sections of the driving shaft.

From the foregoing, it will be seen that the said axle driving pinions 11 are ournaled in w and su ported by the housing 8 independently o the sections of the axle. The housing 8 is in turn journaled in and supported by the compensating gear housing 1, in the following manner. Each part of the housing 'i5 5. is provided with an outwardly projecting flange 17, upon which is supported an adjustable cone 18. Located and-movably supported in the compensating gear housing 1 are the two cones 19, and located between the cones 1S and 19 are suitable roller or ball e, bearings 20. While we have here shown this particular form of bearing, it will be readily understood that any desired form of bearing ibetween the compensating gear and its hous- 2'5 "ing may be used, the main obj ect of which is,

to support or journal the compensating gear in the housing, so that it is held independent of the sections of the drivingshaft, and thus journaled in alinement therewith.

For the purpose of permitting access to the adjustable bearings, and for the purpose of permitting the ready insertion and removal oi the compensating gear in the housing l, the said housing consists ci two longitudinal sections 1a and 1b which are suitably bolted together by members 21. The removal of the upper horizontal section of the compensating gear housing, will permit access to the adjustable nuts 22 for adjusting the bearings of the housing 8.

Journaled in a forward extension 23 of the compensating gear housing, is a drive shaft 24 which carries at its inner end a pinion 25 meshing with, the beveled gear '7, and the shaft 24 is operatively connected with the motor in any suitable manner. The motor is not here shown, as 1t iorms no part oi the present invention.

Referring now to the manner of supporting and journaling the driving Wheels 26a attention is directed te the fact that the axle housing sections 2 and 2' are elongated and pass through the hubs 27 of the said Wheels 26a. The elongated ends 27 oi' these axle housing sections, extend to and preferably in a line with the outer ends 28 of the wheel hubs, as shown. Located upon the extension 27 oi" said axle housing, is a cone-bearing 29, and located around this cone-bearing 29 and'car- 6C' ried by the hub 26 of the wheel, is a conebearing 30. Placed between these conebearings is a s iitable roller or ball bearing 31. At the outer end ofthe hub 26 is also a cone-1 bearing 32, and lon 'tudinally ustable upon an extension 27 is a cone-bearing 33,

erases andbetween these two cone-bearings is located asuitable roller or ball bearing 34. Placed upon the screw-threaded outer end 35 is an adjustable nut 36, and located outside of the nut 36 is a locking member 37. This locking member consists of a ring provided with a plurality of pin openings 38 and an inwardly -extending lip or projection 3S).

The lip or extension 39 projects into a longitudinal slot 40ct the axle housing, which will prevent the locking ring from turning. Formed in the nut 36 is a transverse opening 41 in which is placed a piu 42, and this pin is adapted to passthrough any one of the openings 38 of. the rim. and be secured by a eotterpin 43. The foregoing details are clearly shown in Figs. 4 and 5. By means ot' this construction, the bearings for the supporting and driving wheels 26 are adjustable.

Referring now to 'the manner of. locking the outer ends of the shaft sections to the hubsl 26 of the supporting and driving Wheels, wliichfis clearly shown inthe enlarged Fig. 4, consists in providing a removable member 44 which is adapted to inter-` lock with the hub, and with the outer end of the axle section. For this purpose the outer. edge of the hub 26 is provided with one or more recesses 45, and the member 44 is provided With a corresponding number of projections 46, the arrangement of the projections and the recesses may be reversed, as will be readily understood, so long as the member 44 and the hub are constructed to interlock, that portion of our present invenprojecting elongated portion or sleeve 4?,

which has a longitudinal opening 48 of a shape corresponding to the end 1'6b ci the shaft section and adapted to interlock therewith. The form of the opening 48 and of the end of the shaft section is preferably approximately rectangular, as here shown. This member 44 is shaped to be in the nature of a housing which incloses the adjustable bearing and the end ofthe shaft housing, and also receives the projecting end of the sha-it section, as clearly shown in Fig. 4. The interlocking member is held in position by means of a hub cap 49 which completely in closes the member 44 and is screwed upon the hub 26, as shown at 50. This hub cap is locked in position by means of a screw 51 which is placed at the junction of the inner edge of the cap and the hub, and interlocks with the recesses in both members made to receive the head of the screw, as will be readily understood. ?referably, a 'ber washer 52 is placed between the outer end el the driving shaft and the hub cap, and a for motor vehicles, comprising a dierential understood' that the shaft may be readily l ling out 'the two axle sections sufficiently to tial pinions, and removing the upper horido not in anIy usually the case. OWing to this construc- `housings, a di erential gearing case having Washer 53 is also placed between the adjacentinner ends of the driving shaft sections 16 and 16, as shown in Fig. 1.

From the foregoing description, it will be and quickly removed by simply removing the hub ca 4,9 and the interlocking member 44. It wil also be understood that the differential gearing may beremoved by drawdis'engage the inner'ends from the differenzontal section of the dierential housing. Itl will ialso be observed that the axle sections manner support either' the driving .f whee s or the differentials, as is tion, the driving shaft is not subjected to the Weight of the load, and isnot so liable. to injury. Furthermore, the construction greatly facilitates the assembling of the axle, as the differential gearing` is supported in alinement always to interlock with its inner end.

`Having thus described our inve'nti'on,what we claim and desire to secure by Letters Pat ent, is zl. A supporting and driving mechanism housing havin outwardl r-projecting axle outwardly-projecting hollow hubs supported andjournaled in said housing, supportin T and driving wheelsembracing and journale u on the outer ends of the axle housings, differential gearing in said gear case having pinions c-oncentrically supported by and j ]ournaled in said gear casing, .and two con. I tinuous shaft sections having their inner E ends connected with and Wholly supl orted by said 'pinions, and their outer ems connected with and, wholly supported by said driving and supporting wheels.

2. A supporting and driving mechanism for motor vehicles, comprising a differential housing, having projecting therefrom axle section housings, sup orting and driving wheels journaled on t e outer ends of the axle housings, a differential gearirnii journaled u on and within the diderentja 1housing, an axle sectionscpassing looselyT through the axle housings an having their ends de tachably connected with and supported by the wheel hubs and the differential gearing independent of the axle and differential housings.

3. A dierential gear, comprising a case divided in a direction transverse its axis, a gearing supported therein including planetary pinions, and clamping bolts forming the double function of bearings for said pinions and clamping members for holding the parts of the case together.

4. A supporting and driving mechanism for motor vehicles, comprising a di'erential housing having oppositely projecting axle housings, differential gearing, driving and supporting Wheels embracing and journaled on' and su ported by the ends of the axle housings, t e wheels carrying brake drums, co-acting brake members also supported by said axle housings, and shaft sections extending through the axle ,housings and hav'-V In testimony whereof we affix our signatures in presence of twov witnesses.
